Generate and render a pixel-precise ASCII TUI Line Progress component with complete output blocks (TUI_RENDER, COMPONENT_SPEC, PENCIL_SPEC, PENCIL_BATCH_DESIGN) for Pencil MCP drawing workflows. Use when the user asks to create a line progress in a terminal UI, text-based interface, or Pencil MCP project.

## Purpose
- Produce an ASCII Text UI (TUI) representation of **Line Progress**.
- Always output layout attributes (top/left/width/height, spacing, colors, typography, zIndex).
- Always output Pencil MCP–ready specs and a `batch_design` plan (≤25 operations per call).
## Workflow
1. **Parse input** — Read the input model JSON (widthCols, grid, props, state, style, typography, layout, hotkeys).
2. **Calculate layout** — Convert column/row positions to pixel coordinates using the grid (cellWidthPx=8, cellHeightPx=16).
3. **Render TUI_RENDER** — Build the monospace ASCII art with box-drawing characters, respecting widthCols.
4. **Build COMPONENT_SPEC** — Emit the JSON spec with bbox, style, typography, state, and hotkeys.
5. **Build PENCIL_SPEC** — Emit the canvas and component list for Pencil MCP.
6. **Plan PENCIL_BATCH_DESIGN** — Emit batch_design calls (max 25 ops per call) to create the design in Pencil.
7. **Validate** — Verify bbox dimensions in COMPONENT_SPEC match the TUI_RENDER grid; confirm batch ops stay within the 25-op limit.
## Input Model (Recommended)
```json
{
"widthCols": 70,
"grid": { "cellWidthPx": 8, "cellHeightPx": 16 },
"props": {},
"modelValue": null,
"state": { "focused": false, "disabled": false, "loading": false, "error": null },
"style": {

"textColor": "#111111",
"strokeColor": "#e5e7eb",
"strokeThickness": 1,
"cornerRadius": 12
},
"typography": { "fontFamily": "Inter", "fontSize": 14, "fontWeight": 400, "lineHeight": 20 },
"layout": { "paddingPx": 16, "gapPx": 8 },
"hotkeys": []
}
```

CALL 2:
cmpBg=I(screen,{type:"rect",name:"Line Progress/Background"})
U(cmpBg,{x:24,y:24,width:342,height:96,fillColor:"#ffffff",strokeColor:"#e5e7eb",strokeThickness:1,cornerRadius:12})

U(cmpText,{x:40,y:56,width:310,height:20,textColor:"#111111",fontFamily:"Inter",fontSize:14,fontWeight:600})
```
## Rendering Rules (Component-Level)
Follow the shared rules from `tui-front-ui`:
- No TAB characters.
- Do not exceed `widthCols`.
- Provide a header row, body area, and minimal hotkeys if interactive.
- `disabled=true` must suppress interaction hints.
- `loading=true` must show a stable placeholder.
- `error!=null` must be printed in a single line footer (truncated to width).
## Examples (Must include all output blocks)
